 Module Name:

    CrystalWebPageServer.cpp

 Abstract:

    The app calls GetEnhMetaFileHeader passing
    nSize of 1000. We need to change it to 100 to make the app not crash.
    If we don't do it this will cause memory corruption. Win9x seems to
    be fine with it. Maybe it will crash the app less often in Win9x than
    it does in Win2k.

 Notes:

    This is an app specific shim.
